how much weight can you lose in a week without eating

People always ask: How much weight can you lose in a week?” Well… to answer your question I have good news, awesome news, and bad news.

First onto the good news: YOU CAN LOSE A TON OF WEIGHT IN ONE WEEK

That’s right, you don’t have to be bound to the conventional wisdom of only losing 1 or 2 pounds a week. Extreme weight loss diets can definitely work, but only for a short period of time.

In fact, you can lose up to 15 pounds in one week if you do it correctly.


Yup, you read that correctly, if you follow the methods at the end of this post, all the weight you lose during the week will be pure body fat. The conventional statement that losing more than 2 pounds per week leads to muscle, organ, and hair loss is absolute unicorn shit.

How do I know this? Because some awesome scientists from the American College Of Nutrition back in 1999, conducted a study, which tested 2 groups of people for 12 weeks.

One group only did traditional cardio, while the other group only did weight training. Both groups ate 800 calories a day. At the end of the study, both groups lost large amounts of weight, but the one that only did cardio lost large amounts of lean muscle mass, and the one that only did weight training didn’t lose any muscle mass at all.

So there you go, some hard hitting scientific facts that prove that you will not lose muscle during extreme dieting as long as you lift weights.

Note: And if you don’t have a gym membership or if you don’t have access to any weights, then doing a well-designed bodyweight program like Bodyweight Burn is your next best option.

And lastly, the bad news: YOU HAVE TO EAT VERY VERY LOW CALORIES

So yeah…. you have to eat a ridiculously low amount of calories to lose a lot of weight in a week. I’m talking along the lines of 800 calories a day. The amount that would make any nutritionist hang themselves.

And now, onto the plan, but first, a picture of steaks:

I didn’t want to put a boring picture of a scale, so here’s some delicious steaks. I’m guessing this isn’t the best article to put this picture in

The 2 step plan to lose the maximum amount of weight in a week

Please note that the following plan can be used by both men and woman.

And don’t do this plan if you’re under 18, you’re way too young to be eating such low calories.

I guarantee that if you follow the plan below, you will lose 10-15 pounds(water and fat) in one week:

1) For one week only, eat 800 calories per day.

2) Workout 2-3 times per week with weights. Make sure the weights are heavy and be sure to hit all body parts.

That’s all.

Some notes/tips about the above 2 steps:

  • 800 calories is very little food, for any man, woman, or baby walrus. Because of this, I suggest that you only eat 1 meal per day a la Brad Pilon’s Eat Stop Eat. If you eat one 800 calorie meal per day, then you’ll at least feel somewhat satisfied, but if you split that up into 3 or even worse, 6 meals per day, then you’re not going to fare so well on this one week venture. Yes, this means that you will be fasting 24 hours every day for a whole week. Just remember, you will be burning fat, not muscle.
  • Whenever possible, eat higher protein and eat foods with high water content such as fruits and soups. Also, drink lots of coffee and green tea, since they both tend to blunt hunger quite well.
  • Stick with heavy compound exercises when in the gym. That means no curling and crunching, and if you even step foot on a treadmill, my dumbass radar will go off and I may have to kill you.
  • Above all, keep yourself distracted and out of the kitchen. If you’re constantly prancing around the kitchen and thinking about food, you’re going to fail. So keep yourself busy. Read a book, play some video games, take a nap, work on your tan, or shave your pubes. I don’t care. Just do something that doesn’t involve food.
  • [EDIT 10/6/2014] I should also add that your protein intake needs to be HIGH. Like really high. In fact, the majority of your calories should probably come from protein, fruits, and veggies if you want this diet to be effective. The protein will help keep you full but more importantly also help maintain muscle.

Remember, this is only for one week

I just wanted remind you all, that this sort of extreme weight loss plan is only a temporary plan. The results don’t have to be temporary, but the plan is. Please do not try and do this weight loss plan for more than a week. Doing so is really going to mess with your head and you’ll most likely binge back to your original weight. After one week, transition to a more moderate weight loss plan for the long haul.

I hope you guys now know the answer to “How much weight can you lose in a week?”

Take it to the next level with the Xtreme Fat Loss Diet

Many people have been asking me, “Can I do this for more than 7 days?”

And the answer is no.

The way I laid out the diet above at 800 calories, you can’t do it for more than 7 days.

But there is a more strategic approach you can take where you can go and lose a ridiculous amount of fat in 25 days or less.

The program is called the Xtreme Fat Loss Diet, created by fat loss experts Dan Long and Shaun Hadsall. It’s essentially a much more fleshed out version of the plan I laid out above that will allow you to lose MASSIVE amounts of fat and get as lean as possible in just 25 days. Plus the program incorporates cheat meals so you still get to eat your favorite foods.

What do think of spinning (high intensity cycling). As exercise instead of weight training?
Thank you

I lost 20lbs over the last year and then gained 10lbs back after a family loss. I currently way 170 my goal weight is 135. I tend to get inpatient with the “30 Day challeneges and only make it through two weeks. You said not to do this plan repeatedly, but is it okay to do it 1/4 weeks in a month. With a three week plan in between?

    to be blunt, the fact that you just said you’re “impatient” is why you will never get long term sustainable results. Focus on changing your habits, and stop trying to look for a quick fix.

Alyssa - August 10, 2018

If I run for the workout and follow the 800 calorie diet then will I still lose the weight?and what workouts do you suggest I do?

    Keith - August 11, 2018

    some form of resistance training, if you can, heavy weights – compound movements like squats and bench press

Quinn - August 15, 2018

You said not to do it for longer than a week, but if i need to lose more than 15lbs would it be safe to instead do a week on a week off and alternate until i’ve lost the 45lbs im aiming for?

    Keith - August 16, 2018

    if you need to lose more than 15 lbs then be patient and understand that weight loss is long term game. The weight will come off but not if you try to shortcut your way to success the entire way.

Alexia Kawata - August 19, 2018

How do you make sure the weights hit all body parts?Also, is this something you can only do once, since you can’t go longer then a week? So like just not go 2 weeks in a row? Like maby do it every other week or something? Or its just a one time thing? I really wanna do this help!

    Keith - August 19, 2018

    focus on compound movements like bench press, shoulder press, squats, deadlifts – exercises that hit more than one body part (e.g. don’t focus on bicep curls).

    No, you’re looking for a quick fix/shortcut. This is simply a way to “jumpstart” weight loss. Nothing more.

What if I don’t have any muscle to begin with? I’m a pretty skinny girl already, no toned or proeminent muscles. What would happen if I ate 500-800 kcal per day for a week but did no lifting?

    Keith - August 20, 2018

    If you are pretty skinny, then why are you even doing this?

      Maddie - August 20, 2018

      My boyfriend told me I would look better if I was even skinnier and he comes back in town in exactly one week.
